- RadialColor.itx
- Type: Color, Reflect, Filter.
- Example Object: Plane, Ground.
-
- Overview:
- =========
- Produce non-random circular patterns of color on an object.
-
- At least a 68020 and an FPU are required. The integer version of Imagine is
- not supported, sorry.
-
- Usage:
- ======
- This is a simple texture to implement. All three types of mapping can be
- used at once.
-
- Parameters:
- ===========
-
- Color Red Length, Color Green Length, Color Blue Length
- Reflect Red Length, Reflect Green Length, Reflect Blue Length
- Filter Red Length, Filter Green Length, Filter Blue Length
- -------------------------------------------------------
- RadialColor applies its colors based on the distance from the textures
- axis. Set these values to tell the texture how to color your object.
- The length values tell how many units it takes for a color to range from
- zero to its maximum value of 255. Setting all three RGB values produces
- grays, and setting each to a different value gives a large range of colors.
- A -1 tells the texture to leave that value unchanged.
-
- Smooth Color Repeat
- -------------------------------------------
- Normally the colors start over at 0 from 255. Setting smooth causes it
- to eliminate the sharp color change and replace it with a smooth
- gradation. The default is on. Set it to 0 to turn this feature off.
-
- Color Mixing, Filter Mixing, Reflect Mixing
- -------------------------------------------
- This sets how much to mix the texture color with the objects colors.
- A 1.0 overides the objects colors, lower starts to blend the texture
- in instead of just replacing the colors.
-
- Notes:
- ======
-
- Normally a sphere is a dull object to use with this texture. However,
- try a default sphere and use very small values for the color length.
- Example: R=0.1 G=0.2 B=0.3
- This works because the triangles on a sphere are flat and not curved, so
- the distance from the axis changes very slightly along the surface.
- Phong shading has no effect on this becauseit only modifies the lighting,
- and does not change the actual surface of the object.
